SWINGING- DEVICE FOR BRIDGES OF POWER-DRIVEN VEHICLES.

Application filed October 13, 1924. Serial No. 743,459.

a citizen of the State of Prussia, Germany,

residing at Stuttgart, Olgastrasse 81, Germany, have invented certain new and useful Improvements in a Swinging Device for Bridges of Power-Driven Vehicles, of which the following is a specification.

This invention relates to mechanisn'i for the lateral and backward swinging of bridges or bodies of power-driven dump vehicles, in which the lifting mechanism, which is used for the swinging of the bridge or body, is provided within a casing pivotally mounted to swing around an axis positioned in the longitudinal direction of the vehicle and in which the driving shaft is carried through one of the pivots of the casing.

In con'iparison with known. constructions, in which for instance the rack of a hoist constructed in the form of a lifting device is operatively connected to the swinging bridge, the construction according to this invcntion has the advantage, that the member operating the bridge will be of smaller length and that the time required for the swinging of the bridge or body is rendered shorter.

ln the accompanying drawing an example of carrying this invention into effect shown in which Fig. 1 is a front elevation of the invention, parts of the casing being in section, and 2 is a side view of the device in discharging position.

The shaft a, which is driven by the motor of the vehicle carries on the one of its ends a cog-wheel 7), which meshes with a further cog-wheel c mounted on a jack shaft which also carries a worm cl. The latter meshes with the worn'i-gear e, which drives the cranks g mounted upon the ends of the crank shaft 7'. \Vith the cranks g are connected the operating rods 71, which are con nected by means of the clip oryoke i with the swinging bridge or body A. The bearing Z and m of the casing is have a. common axis, which is positioned in the longitudinal direction of the vehicle, the casing together with the lifting mechanism swinging around this axis during lateral swinging of the bridge. For this purpose the driving shaft a is carried through the bearing Z of the casmg.

The device according to this invention has the special advantage of simplicity and by reason of the crank-motion permits a quick raising and lowering of the swinging bridge.

I claim:

1. A device of the character described having in combination, a vehicle dump body, a casing pivotally mounted to swing about an axis parallel to the longitudinal axis of the vehicle. a power ope "ated drive shaft havii'ig one end extending through the casing and arranged in axial alignment, with the casing pivots, a crank shaft supported within the casing and arranged transversely of the vehicle frame, means within the casing for actuating the crank shaft from the power driven shaft, crank arms upon the ends of the crank shaft, the said arms being connected to the dump body whereby the latter is swung into dumping position upon rotation of said crank shaft.

2. A device of the character described having in combination, a vehicle dump body, a casing pivotally supported below said body to swing about an axis extending longitudinally of said vehicle, a driven shaft extending through the casing and forming one of the pivots thereof, a crankshaft within the casing, a gear upon the inner end of the driven shaft, a jack shaft rotatably mounted in bearings formed in the front and rear walls of the casing, a gear on the jack shaft adapted to mesh with the gear on the driven shaft, a worm on the jack shaft, a. gear on the crank shaft adapted to mesh with the said worm, crank arms upon the ends of the crank shaft, a yoke pivot-ally connected to the bottom of the dump body, and means connecting the crank arms to the ends of the yoke whereby the dump body is swung into dumping position upon rotation of the crank shaft.

in testimony whereof I al'iix my signature in presence of two witnesses.
